RESUMO

A healthy gut during early childhood is important. However, it seems that there are no standard indicators used to assess it. Healthcare professionals (HCPs) were asked via an electronic survey question about gut health indicators (GHIs) for infants and toddlers, in addition to an estimated prevalence of infant's functional constipation (FC) and its management. HCPs from eight countries participated in the survey (Russia (66.0%, 1449), Indonesia (11.0%, 242), Malaysia (6.0%, 132), Mexico (5.7%, 125), KSA (5.1%, 113), Turkey (3.0%, 66), Hong Kong (2.2%, 49), and Singapore (1.0%, 23)). The 2199 participating respondents were further classified into three continents (Asia (20.2%), Europe (68.8%), and others (11.0%)). Most of them were pediatricians (80.3%), followed by pediatric gastroenterologists (7.0%), general practitioners (6.4%), and others (6.3%). The top three preferred GHIs were similar for infants and toddlers: an absence of gastrointestinal (GI) symptoms, effective digestion/absorption as assessed by normal growth, and a general feeling of well-being. The absence of GI-related infection was the least preferred indicator. Most of the respondents reported the prevalence of FC among infants was less than 5%, with the peak incidence between the ages of 3 and 6 months. The reported choices of intervention to manage FC in infants were a change to a specific nutritional solution from a standard formula (40.2%), parental reassurance (31.7%), and lactulose (17.0%). Conclusion: The HCPs in the eight countries preferred the absence of GI symptoms, normal growth for effective digestion and absorption, and general well-being as the gut health indicators in infants and toddlers. The reported prevalence of FC in infants was less than 5%.

RESUMO

Background: The prevalence of functional constipation (FC) among children varies widely. A survey among healthcare professionals (HCPs) was conducted to better understand the HCP-reported prevalence and (nutritional) management of FC in children 12−36 months old. Methods: An anonymous e-survey using SurveyMonkey was disseminated via emails or WhatsApp among HCPs in eight countries/regions. Results: Data from 2199 respondents were analyzed. The majority of the respondents (65.9%) were from Russia, followed by other countries (Indonesia (11.0%), Malaysia (6.0%)), Mexico, KSA (5.1% (5.7%), Turkey (3.0%), Hong Kong (2.2%), Singapore (1.1%)). In total, 80% of the respondents (n = 1759) were pediatricians. The prevalence of FC in toddlers was reported at less than 5% by 43% of the respondents. Overall, 40% of the respondents reported using ROME IV criteria in > 70% of the cases to diagnose FC, while 11% never uses Rome IV. History of painful defecation and defecations < 2 x/week are the two most important criteria for diagnosing FC. In total, 33% of the respondents reported changing the standard formula to a specific nutritional solution, accompanied by parental reassurance. Conclusion: The most reported prevalence of FC in toddlers in this survey was less than five percent. ROME IV criteria are frequently used for establishing the diagnosis. Nutritional management is preferred over pharmacological treatment in managing FC.

RESUMO

Regurgitation, colic, and constipation are frequently reported Functional Gastrointestinal Disorders (FGIDs) in the first few years of life. In 2016, the diagnostic criteria for FGIDs were changed from ROME III to ROME IV. This review assesses the prevalence of the most frequent FGIDs (colic, regurgitation and constipation) among children aged 0-5 years after the introduction of the later criteria. Articles published from January 1, 2016 to May 1, 2021 were retrieved from PubMed and Google Scholar using relevant keywords. A total of 12 articles were further analyzed based on the inclusion and exclusion criteria. This review consists of two studies (17%) from the Middle East, three (25%) from Asia, two (17%) from the USA, three (25%) from Europe, and one (8%) from Africa. Three studies (25%) were based on data obtained from healthcare professionals, while the rest were parent or caregiver reports. About half of the retrieved studies used the ROME IV criteria. Among infants aged 0-6 months, the reported prevalence of colic ranged between 10-15%, whilst that of regurgitation was 33.9%, and constipation was 1.5%. Among infants aged 0-12 months, the reported prevalence of regurgitation and constipation were 3.4-25.9% and 1.3-17.7%, respectively. The reported prevalence of constipation was 1.3-26% among children aged 13-48 months and 13% among children aged 4-18 years. Despite the large variations due to differences in diagnostic criteria, study respondents and age group, the prevalence of infantile colic was higher, while that for infantile regurgitation and constipation were similar using the ROME IV or III criteria.

RESUMO

We report two Hong Kong children with severe generalized epidermolysis bullosa simplex (EBS), the most severe form of EBS, without a family history of EBS. EBS is a rare genodermatosis usually inherited in an autosomal dominant fashion although rare autosomal recessive cases have been reported. Genetic studies in these patients showed that the first case was due to a novel de novo heterozygous variant, c.377T>G (NM_000526.5 (c.377T>G, p.Leu126Arg)) in the KRT14 gene and the second case was due to a rare de novo heterozygous variant c.527A>G (NM_000424.4, c.527A>G, p.Asn176Ser) in the KRT5 gene. To our knowledge, the c.377T>G variant in the KRT14 gene has not been previously reported, and the c.527A>G variant in the KRT5 gene is a rare cause of severe generalized EBS. In severe generalized EBS, infants exhibit severe symptoms at the onset; however, they tend to improve with time. A precise genetic diagnosis in these two cases aided in counseling the families concerning the prognosis in their affected children and the recurrence risk for future pregnancies.

RESUMO

BACKGROUND: Parental self-efficacy has been found to be a critical determinant of the efficacy of interventions intended to enhance the parental management of childhood eczema. OBJECTIVES: The psychometric properties of a translated Chinese version of the Parental Self-Efficacy with Eczema Care Index (C-PASECI) were examined. METHODS: The PASECI was translated in a 2-stage process involving both forward and backward translation. Subsequently, the psychometric properties of the C-PASECI were examined in a cohort of 147 Chinese parents or caregivers of children with eczema. Specifically, the internal consistency, 2-day test-retest reliability and construct validity were assessed. RESULTS: The C-PASECI received a Cronbach's αof 0.97, and the intraclass correlation coefficients of each item ranged from 0.93 to 0.99. Negative correlations were observed among the C-PASECI, Children's Dermatology Life Quality Index and Scoring Atopic Dermatitis Scale scores, indicating the acceptable convergent validity of the C-PASECI. The moderate correlation observed between the C-PASECI and General Self-Efficacy Scale (Pearson's r = 0.53, p < 0.001) reflected the acceptable concurrent validity of the C-PASECI. The results of confirmatory factor analysis supported the factorial validity of the C-PASECI. CONCLUSION: The C-PASECI appears to be a reliable and valid measure of parental self-efficacy in Chinese parents or caregivers of children with eczema.

RESUMO

BACKGROUND & AIMS: The incidence of inflammatory bowel disease (IBD) is increasing in Asia, but little is known about disease progression in this region. The Asia-Pacific Crohn's and Colitis Epidemiology Study was initiated in 2011, enrolling subjects from 8 countries in Asia (China, Hong Kong, Indonesia, Sri Lanka, Macau, Malaysia, Singapore, and Thailand) and Australia. We present data from this ongoing study. METHODS: We collected data on 413 patients diagnosed with IBD (222 with ulcerative colitis [UC], 181 with Crohn's disease [CD], 10 with IBD unclassified; median age, 37 y) from 2011 through 2013. We analyzed the disease course and severity and mortality. Risks for medical and surgical therapies were assessed using Kaplan-Meier analysis. RESULTS: The cumulative probability that CD would change from inflammatory to stricturing or penetrating disease was 19.6%. The cumulative probabilities for use of immunosuppressants or anti-tumor necrosis factor agents were 58.9% and 12.0% for patients with CD, and 12.7% and 0.9% for patients with UC, respectively. Perianal CD was associated with an increased risk of anti-tumor necrosis factor therapy within 1 year of its diagnosis (hazard ratio, 2.97; 95% confidence interval, 1.09-8.09). The cumulative probabilities for surgery 1 year after diagnosis were 9.1% for patients with CD and 0.9% for patients with UC. Patients with CD and penetrating disease had a 7-fold increase for risk of surgery, compared with patients with inflammatory disease (hazard ratio, 7.67; 95% confidence interval, 3.93-14.96). The overall mortality for patients with IBD was 0.7%. CONCLUSIONS: In a prospective population-based study, we found that the early course of disease in patients with IBD in Asia was comparable with that of the West. Patients with CD frequently progress to complicated disease and have accelerated use of immunosuppressants. Few patients with early stage UC undergo surgery in Asia. Increasing our understanding of IBD progression in different populations can help optimize therapy and improve outcomes.

RESUMO

We reviewed etiology and outcome of consecutive neonates admitted to a neonatal unit for investigation of parent-reported fever (116 neonates over 24 months). Tympanic temperature was measured at the emergency department (Te) and core temperature at the neonatal unit (Tn). Microbials were isolated in 27 patients (23%); Te and Tn were both <38°C in 13 (48%) of the 27 patients. Microbial isolation was associated with older median age (16.7 vs. 8.0 days, p = 0.004), empirical antibiotic commencement (p = 0.0003) and longer hospital stay (median 8 vs. 4.0 days, p = 0.004). Compared with respiratory viral infection, patients with bacteremia had high C-reactive protein (p = 0.005) and likely to have comorbidity of meningitis (p = 0.077). Te ≥38°C had the highest sensitivity, positive likelihood ratio and positive and negative predictive ratios for bacteremia. Parent-reported fever was associated with a 3% incidence of meningitis, 6% of bacteremia and 9% of urinary tract infection. The majority of neonates with parent-reported fever do not have serious bacterial infection. Nevertheless, recommendations about threshold of antibiotic initiation are difficult, and empirical systemic antibiotic coverage must be commenced in those neonates with Te ≥38°C or elevated C-reactive protein.

RESUMO

OBJECTIVE: The rising incidence of inflammatory bowel disease in Asia supports the importance of environmental risk factors in disease aetiology. This prospective population-based case-control study in Asia-Pacific examined risk factors prior to patients developing IBD. DESIGN: 442 incident cases (186 Crohn's disease (CD); 256 UC; 374 Asians) diagnosed between 2011 and 2013 from eight countries in Asia and Australia and 940 controls (frequency-matched by sex, age and geographical location; 789 Asians) completed an environmental factor questionnaire at diagnosis. Unconditional logistic regression models were used to estimate adjusted ORs (aOR) and 95% CIs. RESULTS: In multivariate model, being breast fed >12 months (aOR 0.10; 95% CI 0.04 to 0.30), antibiotic use (aOR 0.19; 0.07 to 0.52), having dogs (aOR 0.54; 0.35 to 0.83), daily tea consumption (aOR 0.62; 0.43 to 0.91) and daily physical activity (aOR 0.58; 0.35 to 0.96) decreased the odds for CD in Asians. In UC, being breast fed >12 months (aOR 0.16; 0.08 to 0.31), antibiotic use (aOR 0.48; 0.27 to 0.87), daily tea (aOR 0.63; 0.46 to 0.86) or coffee consumption (aOR 0.51; 0.36 to 0.72), presence of hot water tap (aOR 0.65; 0.46 to 0.91) and flush toilet in childhood (aOR 0.71; 0.51 to 0.98) were protective for UC development whereas ex-smoking (aOR 2.02; 1.22 to 3.35) increased the risk of UC. CONCLUSIONS: This first population-based study of IBD risk factors in Asia-Pacific supports the importance of childhood immunological, hygiene and dietary factors in the development of IBD, suggesting that markers of altered intestinal microbiota may modulate risk of IBD later in life.

RESUMO

BACKGROUND: Specific immunoglobulins G and A (IgG and IgA) for common food items have been extensively measured as surrogate markers of food allergy, and dietary avoidance based on the test results advocated. AIM: We reviewed the prevalence of specific food IgG and IgA in children with eczema and evaluated outcome of dietary avoidance in these children. METHODS: Specific immunoglobulins of 96 food items were measured for 30 consecutive atopic dermatitis (AD) patients and disease severity [SCORing atopic dermatitis (SCORAD) and Nottingham eczema severity score (NESS)], Children Dermatology Life Quality Index (CDLQI), skin hydration (SH), transepidermal water loss (TEWL), topical corticosteroid and oral antihistamine usage were evaluated. Twenty seven of these patients received dietary avoidance advice based on IgG and IgA data. General acceptability of treatment (GAT) was documented at the end of 3 months. RESULTS: There were generally no correlations among levels of IgG or IgA of the 96 food items and disease severity, quality of life, SH or TEWL. Two-third patients reported very good or good and one-third reported fair or poor GAT following dietary avoidance advice. There was no difference in any clinical parameters between the two groups following dietary avoidance. Patient with lower sunflower seed IgA (p = 0.043), casein IgG (p = 0.041), milk IgG (p = 0.037) or whey IgG (p = 0.014) had improved SCORAD and objective SCORAD following dietary advice. CONCLUSION: Children with AD are sensitized to many food allergens via IgG and IgA mechanisms. Levels of food IgG or IgA do not seem to correlate with any clinical parameters in AD. Subjectively, two third of patients accepted dietary manipulations as very good or good for their AD. Objectively, dietary avoidance had few clinical effects on the clinical parameters. Sensitization should not be generalized to mean allergy to common food.

RESUMO

A bezoar is a mass found trapped in the gastrointestinal system. The condition may be associated with pica, especially in developmentally retarded children. Clinical manifestations are usually nonspecific. Endoscopic diagnosis and removal of the foreign materials is often indicated. Occasionally, severe complications may occur. We report two cases to illustrate the clinical features and complications in these children. In the first case, a reliable history was not obtained in the developmentally delayed girl which precluded prompt diagnosis, but the grossly dilated stomach on plain abdominal radiograph gave clues to an underlying insidious mechanical obstruction of upper gastrointestinal tract. In the second case of a normal child, the unrelenting symptoms and weight loss prompt further investigations which revealed the diagnosis. Literature on pediatric bezoar is reviewed. Oesophagoduodenoscopy is the investigation of choice for diagnostic confirmation, but surgical facilities must be available to deal with acute complications.

RESUMO

BACKGROUND: Recent studies presented a contradictory approach for the investigation of pediatric patients with an isolated increase in alanine transaminase. While classical teaching advised for a thorough investigation, recent studies suggested the yield on further investigation was low and thus not necessary. Yet the approach to the same clinical problem may need to be different due to variable disease prevalence rates among different ethnic populations. For the population with a higher prevalence rate of genetic liver diseases like Wilson's disease, an abnormal liver function may be the first presenting feature for some patients. METHODS: We reviewed 10 Chinese children with Wilson's disease who were diagnosed at a presymptomatic stage because of an isolated persistent elevation of alanine transaminase. RESULTS: All 10 patients did not have overt symptoms of liver impairment or neurological deficit. They were picked up incidentally with an abnormal liver function test. All patients were started on treatment shortly after diagnosis, and they remained well and symptom-free on the latest follow-up. CONCLUSIONS: This case series illustrated that an isolated persistent elevation of alanine transaminase is an important clue to the early diagnosis of pre-symptomatic Wilson's disease. It is particularly relevant in the Asian population where the disease is more prevalent.

RESUMO

BACKGROUND & AIMS: Inflammatory bowel diseases (IBD) are becoming more common in Asia, but epidemiologic data are lacking. The Asia-Pacific Crohn's and Colitis Epidemiology Study aimed to determine the incidence and phenotype of IBD in 8 countries across Asia and in Australia. METHODS: We performed a prospective, population-based study of IBD incidence in predefined catchment areas, collecting data for 1 year, starting on April 1, 2011. New cases were ascertained from multiple overlapping sources and entered into a Web-based database. Cases were confirmed using standard criteria. Local endoscopy, pathology, and pharmacy records were searched to ensure completeness of case capture. RESULTS: We identified 419 new cases of IBD (232 of ulcerative colitis [UC], 166 of Crohn's disease [CD], and 21 IBD-undetermined). The crude annual overall incidence values per 100,000 individuals were 1.37 for IBD in Asia (95% confidence interval: 1.25-1.51; 0.76 for UC, 0.54 for CD, and 0.07 for IBD-undetermined) and 23.67 in Australia (95% confidence interval: 18.46-29.85; 7.33 for UC, 14.00 for CD, and 2.33 for IBD-undetermined). China had the highest incidence of IBD in Asia (3.44 per 100,000 individuals). The ratios of UC to CD were 2.0 in Asia and 0.5 in Australia. Median time from symptom onset to diagnosis was 5.5 months (interquartile range, 1.4-15 months). Complicated CD (stricturing, penetrating, or perianal disease) was more common in Asia than Australia (52% vs 24%; P = .001), and a family history of IBD was less common in Asia (3% vs 17%; P < .001). CONCLUSIONS: We performed a large-scale population-based study and found that although the incidence of IBD varies throughout Asia, it is still lower than in the West. IBD can be as severe or more severe in Asia than in the West. The emergence of IBD in Asia will result in the need for specific health care resources, and offers a unique opportunity to study etiologic factors in developing nations.

RESUMO

BACKGROUND: Dietary assessment is crucial for monitoring nutritional status of young children. This study applied a modified Chinese food frequency questionnaire (FFQ) to assess nutrient intakes of young picky-eating Hong Kong children. METHODS: Nutrient intakes were obtained by FFQ and 3-day food record (3DFR) in 29 picky-eating children aged 44.8±9.2 months who participated in a randomised controlled trial of a new milk formula. RESULTS: When compared with 3DFR, FFQ over-reported energy intake by 283 kcal (26.5%) at baseline and 237 kcal (21.4%) at end-of-study, and also overestimated intakes of carbohydrates, proteins and fats. At baseline, FFQ and 3DFR classified 34.4%-65.5% of subjects into the same tertiles for most nutrients. These methods showed weak-to-moderate agreement in measuring most nutrients, with 3DFR showing a trend towards a systematic increase in the differences with increasing nutrient intake. CONCLUSION: Our FFQ shows promising results for assessing nutrient intakes in picky-eating Chinese preschoolers.

RESUMO

OBJECTIVES: Traditional Chinese medicine (TCM) is popular as an alternative medicine in children with atopic dermatitis (AD). A concoction of five herbs in a capsular preparation has been confirmed to be efficacious in improving the quality of life and sparing topical corticosteroid usage. We evaluated the clinical efficacy and tolerability of the same concoction in syrup form. METHODS: This was a prospective self-controlled trial set in the pediatric dermatology clinic of a teaching hospital. Children aged 4-7 years with moderate-to-severe AD received 20 ml of TCM syrup daily. Clinical parameters and laboratory markers were measured before and at 2 weeks, 7 weeks and 12 weeks of treatment, and at 4 weeks after completion. Disease severity was evaluated by the SCORing Atopic Dermatitis (SCORAD) index and quality of life by the Children's Dermatology Life Quality Index (CDLQI). Blood was obtained for a complete blood count, total IgE, eosinophil count, and biochemical studies prior to and after 3 months of TCM usage. RESULTS: Twenty-two patients participated in the study. There were significant improvements in the objective SCORAD, pruritus and CDLQI scores 4 weeks after study completion. There was no change in sleep score or amount of topical steroid consumption. No biochemical evidence of any adverse drug reaction was observed during the study period. The TCM syrup was generally palatable and well tolerated by the children. Adverse effects were generally mild but two patients with rash withdrew during the study. CONCLUSION: The palatability means that further evaluations and dosage studies of the concoction will be possible in young children.

RESUMO

Food atopy is important but inadequately studied among children with atopic dermatitis (AD). We evaluated whether any association existed between AD severity, quality of life, total IgE, eosinophil counts, and the number of food items sensitized. Specific IgE of ten common food items was measured for a group of consecutive AD patients (n=85) enrolled during a randomized trial and correlated the findings with eczema severity. Twenty-four patients (28%) were negative for any of the ten common food items. The most commonly sensitized foods were shrimp (54%), egg white (43%), wheat (42%), and peanut (41%). Atopy to beef as a protein and orange as a fruit were least common among the food items studied, even among patients positive for 8-9 IgE items. Patients with severe AD (objective SCORAD>40) were more likely to be positive for at least one of the food items (Yates corrected p=0.024 for ≥1 food-specific IgE in severe vs. moderate AD, OR 3.42 and 95% CI 1.15-10.32); and for at least seven of the food items (p=0.001 for ≥7 food-specific IgE vs. nil with OR 11.67 and 95% CI 2.29-67.77), respectively. The Spearman coefficients between the number of positive food-specific IgE and total SCORAD, objective SCORAD, area of AD involvement, Children's Dermatology Life Quality Index (CDLQI), total IgE levels, and eosinophil counts were 0.42 (p<0.001), 0.45 (p<0.001), 0.50 (p<0.001), 0.17 (p=0.116), 0.80 (p<0.001), and 0.22 (p=0.043), respectively. Specific IgE levels for beef correlated with all the other food-specific IgE levels, including cow's milk (ρ=0.061, p<0.001) and soy (ρ=0.70, p<0.001). The number of common food items sensitized correlated with disease severity, extent, and total IgE levels. IgE sensitization to beef protein is unlikely in the majority of children with AD, but its serum IgE level is associated with disease severity and risk of sensitization to other foods.

OBJECTIVE: To explore the prevalence of common food and aeroallergens sensitization in early childhood skin diseases. and to compare the pattern of common food and aeroallergens sensitization before and after 6 months among infants with atopic dermatitis (AD). METHODS: All skin prick tests (SPTs) performed on children pound18 months of age managed at the pediatric dermatology clinic of an university-affiliated teaching hospital over a 16-month period were examined. RESULTS: There was generally no difference in the pattern of sensitization to common food and aeroallergens between AD patients and non-AD young children with miscellaneous dermatological or gastrointestinal conditions. Dust mites were the only common aeroallergens in these patients; whereas egg and peanuts were the common sensitizing food allergens. Cat and dog fur as aeroallergens, soy bean, orange and beef as food allergens were relatively uncommon among the studied subjects. In AD, infants pound 6 months were generally naive to aeroallergens but became sensitized to the D. Pteronyssinus in the next 12 months of age. 80% of these infants were not sensitized to cow's milk and none sensitized to soybean. CONCLUSION: Atopic sensitization to common allergens was common in early childhood with or without AD. Majority of young infants were not sensitized to milk, and develop eczema before they show atopy to the milk or soy allergens.

RESUMO

The incidence of eczema has been increasing in developed countries. Environmental and hygiene factors have been incriminated. Although air and food pollution with heavy metals have been considered as possible culprits, these factors have never been investigated in Hong Kong. To evaluate if quality of life and eczema severity are associated with abnormal serum levels of six common heavy metals, namely, cadmium, lead, mercury, selenium, copper and zinc. Serum or whole blood was taken for measurement of six heavy metals from patients referred to the pediatric dermatology clinic. Eczema severity (SCORAD and NESS) and quality of life (CDLQI) were recorded. A total of 110 patients with eczema and 41 patients with miscellaneous skin conditions were recruited. Serum levels of the six heavy metals were generally within the upper limits of local reference ranges. Zinc levels were below the lower reference limit of 9.4 mum in 66 patients with eczema (60%) and 22 non-eczema patients (53%). Forty-four patients with eczema (40%) and 24 (58%) in non-eczema group had low copper levels. In eczema patients, lead levels were generally within normal limits but their levels were positively correlated with poor quality of life (CDLQI: r = 0.22 and p < 0.05), disease severity (objective SCORAD: r = 0.33 and p < 0.005; NESS: 0.20, p < 0.05), eosinophil count and log-transformed IgE. Copper/zinc ratio also correlated with NESS and CDLQI and was generally higher than non-eczema skin diseases. Our findings help reassure parents that levels of heavy metals generally do not exceed the local reference ranges for toxicity. However, lead levels have significant correlations with disease severity, quality of life and atopy. Low zinc and copper levels are commonly found in pediatric skin diseases and their significance needs to be determined.

RESUMO

INTRODUCTION: Recalcitrant childhood atopic dermatitis (AD) causes significant morbidity and may necessitate systemic treatment with immunomodulating agents such as azathioprine. We reviewed the clinical and biochemical effects of this agent in children and adolescents receiving this treatment between November 2005 and December 2007. METHODS: The clinical efficacy of azathioprine, and its hematological and biochemical effects (serum IgE level, liver and renal function), were assessed at 3 months and 6 months in 17 cases of recalcitrant AD. Disease severity was evaluated with the SCORing Atopic Dermatitis (SCORAD) score which has two components, namely (1) the objective SCORAD which measures the extent (percentage of body surface area involved) and intensity of the lesions, and (2) visual analog scales which measure the subjective symptoms of pruritus and sleep loss. RESULTS: There were nine males and eight females with a mean (SD) age of 16.1 (3.9) years. Compared with baseline, significant improvements were observed at 3 months (n = 17) and 6 months (n = 16) in SCORAD (p = 0.002; p < 0.001), objective SCORAD (p = 0.002; p = 0.001), extent (p = 0.001; p < 0.001), pruritus (p = 0.004; p = 0.001) and dryness (p = 0.033 at 6 months). Compared with males, objective SCORAD was significantly lower in females (p = 0.009) at 6 months. Azathioprine was stopped in one female after 4 months due to lack of efficacy. Serum total IgE (p = 0.006) was significantly lower at 6 months. The frequency of oral antihistamine usage and Staphylococcus aureus carriage were also significantly reduced (p = 0.031 and p = 0.016, respectively). Mild transient elevation of glutamic-pyruvic transaminase in one patient which became normalized on cessation of the drug, and mild elevation of serum bilirubin in two other patients were observed. CONCLUSIONS: Azathioprine reduced the disease severity of AD within 3 months of use in these children. Better efficacy was observed in females at 6 months. Adverse hematologic and biochemical effects appeared acceptable but longer-term monitoring is desirable.
